Experimental study of dynamic response of passive flapping hydrofoil in regular wave

The hydrofoil harnesses wave energy and converts it into thrust. In this paper, we present the results of the first experimental study investigating the dynamic behavior of a fully passive foil with spring-loaded pitch and heave in regular waves. Our study shows that the real-time load signal is multi-harmonic with strong superposition,...

Long-term assessment of wave conditions and wave energy resource in the Arctic Ocean

It was recently shown that the Arctic has been warming much faster than the rest of the globe during the last decades. This warming has reduced the ice extent significantly, which will strongly impact the wave climate in the Arctic regions, thus affecting the design of marine structures, operations, and energy resources. This study focuses on...

Time Domain Modeling of a Point Absorber

The demand for renewable energies is rising due to climate goals and high oil prices. Not only the established renewable sources like wind and solar are interesting to exploit. There is a vast amount of energy stored in the world’s oceans. To harvest this energy, one needs a Wave Energy Converter (WEC). There<br/>are already some prototype WECs...

Nearshore submerged wave farm optimisation: A multi-objective approach

To be commercially viable, wave energy converters (WECs) will need to be deployed in arrays or “wave farms” to generate significant amounts of energy and to have the costs of these farms minimised. However, when designing a wave farm, there are a number of trade-offs to be made between competing objectives; for example, between the power...

Spatio-temporal assessment of climate change impact on wave energy resources using various time dependent criteria

The wave energy resources in the Indian Ocean can be considered as a potential alternative to fossil fuels. However, the wave energy resources are subject to short-term fluctuations and long-term changes due to climate change. Hence, considering sustainable development goals, it is necessary to assess both short-term (intra-annual) variation...

Hydrodynamic performance of a multi-Oscillating Water Column (OWC) platform

A rectangular barge consisting of multiple oscillating water columns (OWCs) is considered in this paper, hereinafter referred to as a multi–OWC platform. Each OWC chamber is enclosed by two partially submerged vertical walls and the deck of the platform. An incident wave produces oscillation of the water column in each OWC chamber and hence air...

Wave energy in the Netherlands: Past, present and future perspectives

With the renewable targets of 2020 reaching ever closer, Europe is continuing its ambitious plans for 2030 of developing innovative projects that assist tackling climate change and increase renewable energy integration. The Netherlands are trying to develop their renewable energy portfolio, to create a viable long-term decarbonized sustainable...

Generator Design for the Symphony Wave Power Device

Wave power is a large untapped source of renewable energy. There is a wide variety of wave energy converters and one of them is the Symphony Wave Power device. The aim of this thesis is to find the best generator design for the Symphony. There is some research available on generator designs for wave energy converters but the Symphony is a unique...

A Wideband Millimeter-Wave Power Amplifier With 20 dB Linear Power Gain and +8 dBm Maximum Saturated Output Power

Floating breakwaters: Literature review

The purpose of this report is to find out which floating breakwaters can be utilized in open sea conditions and what can be expected of them. Since every breakwater interferes with the energy of the waves, it is logical that a probable power generation function of floating breakwaters is also investigated. This report is a global review of the...
